Kanye West shelled out a small fortune for some ad space during the Super Bowl -- in a limited capacity, anyway -- and it seems to have paid off ... at least according to him.

Ye announced his haul from Sunday on social media to kick off the new week -- and single-day figures that he's citing are pretty good ... around $19 million is what one of his reps says Yeezy.com made after his stripped-down SB spot.

He posted a screenshot of a text he apparently received, which breaks down what items were sold and the dollar amount for each. There's 4 different products that KW and co. were really pushing, it seems, and those include a top, pants, a T-shirt and YZY pods.

The pods are basically foldable futuristic socks that you can wear as actual footwear.

Funny enough, Kanye seems to have had a great sale on his website ... these items he's hawking are all on sale for a measly $20. Yep ... even now, you can get 'em at that price.

If these numbers are accurate -- then yeah ... Kanye low-key cleaned up on his inventory ... and it would appear his "commercial" (if you can call it that) actually worked wonders.

ICYMI ... the dude had one of the most bare-bones ads of all time -- which only aired in certain markets during the Super Bowl broadcast -- and it featured Ye literally filming himself in the back of a car, selfie-style, and giving a quick explainer of what he was selling.

Like we said, it was as basic as it could be -- and yet, it seems to have done the job!

Some are calling Ye a marketing genius over this ... and others are grumbling that the dude still has a customer base that'll buy his stuff -- even after everything he's said/done by now.
